Perseverance Edges Past Opportunity's Mars Distance Record by 0.06 Kilometers

NASA's Perseverance rover passed Opportunity's off-world driving record on Oct. 11, reaching 45.22 kilometers (28.10 miles) against Opportunity's 45.16 kilometers (28.06 miles), a margin of 0.06 kilometers.

NASA's Perseverance blog posted the milestone on Oct. 12 and dated it to the 2,006th Martian day of the mission. Guinness World Records lists it as the greatest distance travelled on another world.

The drive that took it over the line

The record-setting drive covered 91.31 meters (299.6 feet) from a spot called Lac de Charmes on the Jezero Crater rim toward a region named Idubi, Guinness reports. It moved the odometer from 45.13 to 45.22 kilometers. The 0.06-kilometer margin is less than the length of one maximum drive: NASA says Perseverance can cover up to 412 meters in a single Martian day.

Opportunity explored Mars from 2004 to 2018. NASA says Perseverance covered in about five and a half years what took Opportunity almost 15.

Why it got there in less than half the time

Guinness says Perseverance's top speed matches Opportunity's, so the difference is navigation. Perseverance carries an added onboard computer, the Vision Compute Element, which runs AutoNav, software that images terrain while driving, builds a 3D hazard map and plans a path between waypoints. NASA says AutoNav processes 600,000 measurement points per look, against 20 for the Sojourner rover.

The number that matters here is the share of distance driven under that software. NASA says more than 90 percent of Perseverance's total distance used AutoNav to evaluate terrain, against about 5 percent for Opportunity and its twin Spirit. Mark Maimone, deputy team chief for robotic operations on Perseverance, said in NASA's post: "Perseverance is a better driver than the one that landed." Steven Lee, project manager of the Curiosity and Perseverance rovers at NASA's Jet Propulsion Laboratory, said it is "an honor to be working on Perseverance at a moment when the technology has evolved to the point that drives like these are routine."

Hardware life against the plan

Lee said the original mission "called for no more than 12.4 miles of driving," about 20 kilometers. Guinness reports the rover's motors were rated for 20 kilometers and are now expected to last at least 100 kilometers. The rover is at 2.26 times its design figure.

Lee said in NASA's post that "with all mobility systems fully operational and favorable extended-ground-life test results, we expect Perseverance to keep adding to this record for many years to come." NASA's post does not publish the wheel-wear data behind that statement, and the 100-kilometer figure appears in Guinness's article, not in NASA's.

Autonomy claims on Earth sit under a different standard. NHTSA's file on Tesla robotaxis in school zones covers roughly 1,000 vehicles on public roads, where a mis-planned path can hit a person. Space systems also have exposed ground segments: Starlink ground sites burned in Poland and Bulgaria 16 days apart.

Curiosity, active since August 2012, has driven about 38 kilometers, per Guinness, which expects it to eventually match Opportunity's distance. The date it does so is the number to watch; neither source gives one.
